I am working with a API which will get the node by Id with all childnode. But I am getting the node information only, not getting the childnode or any navigation property unless I clear the memory cache from Umbraco backoffice setting.

Example:

You can see in screenshot (1,2) my location with child POIs and Api. POIs is empty in api response.

But I click in reload in Memory cache section in screenshot 3. Then the api is getting the data will all POis.

I am think to clear the memory cache when call the api. Do you know how to clear Memery cache? or would you please suggest a good way to get the child information?

My location & API:
